Solar radiation analysis of a public building. Multipurpose common public space analysis with parametric louvers to control sun exposure and radiation.
In vitro bacterial culture
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.

centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Amphora sp. algae under microscopic view pattern, Diatoms, phytoplankton, fossils, silica, golden yellow algae

Raspberry rust is a malignant disease caused by the phytoparasitic fungus Phragmidium rubi-idaei. This pathogen forms small ulcers on the leaves through which a huge mass of orange spores breaks through. Under a microscope, this pathogen does not look so sinister.
Blue Square wooden box filled with blue book replicas
Photomicrograph of Volvox globator, a green algae in various stages of development. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
